US members-only retail giant Costco has opened its second Australian store in Sydney, with some staggeringly cheap tech bargains. We dive in.

How about a 3TB USB hard drive for $169? (27% cheaper than we could find it anywhere else.) Or a high-powered Intel Core i7 HP dv6-6012tu notebook for $699.99? (23% cheaper than the lowest price we could find elsewhere.)

We've catalogued and compared the best tech deals we found at the end of this article.

Inside the cavernous warehouse in Sydney's bargain outlet suburb of Auburn, Costco is a bit like a cross between an Aldi, a Bunnings and an Ikea. It's Aldi in that stuff is sold on pallets. There are no neatly stacked shelves with a bit of this and that like in Woolworths.
